SNAP FOR HOLDING GLASSWARE.

SPEOIFICATTON forming part of Letters Patent N 0. 508,854, dated November 14, 1893.

Applicationfiled August 1, 1893. Serial No. 482,082. (No model.) a

To all whom it may concern:

Be t known that I, THEODORE O. STEIMER, of Fmdlay, in the county of Hancock and State of Ohio, have invented a new and usefullmprovement in Snaps for Holding Glassware, of which the following is a full, clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification, in which Figure 1 is a central'vert-ical section oi my improved snap; and Fig. 2 is a plan view of V the same.

My invention relates to the snaps employed 1n holding partially-finished glass artlcles whlle reheating, glazing or polishing the same, and it consists in an improved construction and arrangement of parts whereby the rod which opens the jaws serves also,

when released, to close and lock the jaws upon the article to be retained.

In the drawings, in which similar numerals indicate corresponding parts, 2 represents the tubular handle of the snap, within which s inclosed the usual operating rod 3, which is normally retracted by a spiral spring 4,

. which abuts at one end against the end of serves to open and close them.

the tube 2, and at the other end against the button 5 at the; lower end of the operating rod. A case 6 incloses the spring, being secured about the lower end of the tube 2, and serves as a guide for the enlarged portion or button 5 of the rod which closes the lower- At the upper end of the rod 18 carried a circular disk 7, which works in end of the case.

thecentral opening between the jaws and are pivoted between lugs 8 projecting from the base-plate 9 secured about the upper end the article operated upon.

of the tube 2, and, as shown in Fig. 2, are

arc-shaped and provided with a groove or recess lO'to fit about'and inclose the base of Projecting downwardly from the jaws are arc-shaped inwardly-beveled lips 11,

provided on their lower outer edges with arc-shaped grooves which fit snugly upon an annular-shoulder 12 on the base-plate and are thereby centered accurately.

. closed position,

The operation of the device is obvious. The disk normally holds the jaw locked in as shown in Fig. 1, as it .the lips 11.

. These jawspresses outwardly upon the lower ends of When, however, the button and rod are forced upwardly, the disk contacting with the in wardly extendingbases of thejaws, swings them-outwardly and opens the'snap for the receptionof the article.

The advantages of the device are numerous. The disk;ser'ves both to lock the jaws in'closed position and to open the same. The article is heldevenly and with equal pressure on all sidesfand thus the liability to uneven revolving of the article removed. The seating of the jaws upon the annular shoulder takes up any'wear and centers the jaws, while the entire device is simple and cheaply made.

As many jaws may be used as desired, and man y other variationswill suggest themselves to those skilled {inthe art without departure from my invention, since What I claim is 1. A snap having hinged jaws and a disk arranged to positively open and close said jaws; substantially as described.

2. A snap having hinged jaws provided with beveled lips, and a disk arranged to ride upon the lips and close the jaws; substantially as described.

3. A snap having hinged jaws provided with recessed portions arranged to seat upon an annular shoulder on the base-plate of the snap; substantially as described.

'4. A snap having a tubular handle, jaws pivoted at its upper end and havinginwardly projecting bases, anda rod passing through the handle and arranged to abut against the bases and swing the jaws open; substantially as described.

5. A snap having a tubular handle, jaws pivoted at its upper end and having inwardly I projecting bases and depending beveled lips,

a rod having adisk arranged to contact with the bases and lips,an'd a spring. arranged to retract-the rod; substantially as described.

In testimony whereof I have hereunto set my hand.

THEODORE o. STEIMER.
